Phosphorous Magnetic Resonance Spectroscopy of Heart

Left Ventricular Dysfunction

Heart needs constant supply of energy to continue working. Phosphorus magnetic resonance spectroscopy allows us to measure energy produced in the heart. The purpose of this study is to determine if the energy production is reduced in failing heart.

Characterization of Patients With Post-ischemic Left Ventricular Dysfunction

Left Ventricular Diastolic Dysfunction

This is an observational, prospective, multicenter study (12 hospitals belonging to the Italian Cardiology Network) in patients with STEMI ST elevation myocardial infarction (STEMI) treated successfully with primary percutaneous coronary intervention (PCI), that will be followed for 12 month after the acute event, in order to ascertain the predictive value of myocardial viability measured with cardiac magnetic resonance (1.5 T; based on the transmural distribution of late enhancement in the infarcted segments) for the identification of left ventricular (LV) remodelling (REM) 6 months after STEMI.

Sleep-Disordered Breathing in Heart Failure - The SchlaHF-Registry

Congestive Heart FailureLeft Ventricular Systolic Dysfunction

Objective target of the registry is to investigate the prevalence of SDB as well as the clinical characteristics of patients with and without SDB as well as the predominant type of sdb. For this purpose data from patients suffering from chronic, symptomatic heart failure with impaired left ventricular ejection fraction will be collected prospectively.

Clinical Trial in Patients With Hypertension and Left Ventricular Dysfunction

HypertensionCardiac Arrhythmias3 more

Arterial hypertension causes adverse effects on the entire cardiovascular system, with effects centrally such as diastolic dysfunction and structural changes of the left ventricle and, peripherally such as endothelial dysfunction and increased thickness of the vessels. Co-existing diseases, such as diabetes mellitus, renal dysfunction, sleep apnea, etc. further aggravate the prognosis of these patients. In addition the rate of patients aged > 65 years suffering from un-diagnosed or diagnosed arterial hypertension was 78% for women and 64% for male patients. This population consists from elderly or very elderly patients (over 65 and 80 years respectively) who exhibit more comorbidities and probably less compliance with antihypertensive therapy. Finally, at every age the disease and its effects can affect the quality of life of patients. The main purpose of this study is to investigate the efficacy of antihypertensive therapy (irbesartan alone or in combination with amplodipine and carvedilol) on the cardiovascular system (diastolic left ventricular function, the function of the endothelium (FMD) and the thickness of the common carotid artery). The secondary objective of the study is to monitor the quality of life (Quality of Life - QoL) of patients. Additionally the investigators will seek the correlation of results with co-morbidities, compliance, and patient age.

Heart FailureCongestive3 more

The purpose of this study is to characterize current management of patients with either heart failure or prior myocardial infarction and left ventricular dysfunction and to assess the effect of education, specific clinical guidelines, reminder systems, comprehensive disease state management tools, benchmarked quality reports, and academic detailing on the use of evidence-based heart failure therapies in cardiology practices. This study is a quality improvement initiative that is being conducted through review of patient records.

The Use of Myocardial Deformation Imaging

Myocardial Viability in Ischemic Left Ventricular DysfunctionPrediction for Improvement in Cardiac Function After Revascularization Therapy

Myocardial deformation imaging allows analysis of myocardial viability in ischemic left ventricular dysfunction. This study will evaluate the predictive value of myocardial deformation imaging for improvement in cardiac function after revascularization therapy in comparison to contrast-enhanced cardiac magnetic resonance imaging (ceMRI). In 55 patients with ischemic left ventricular dysfunction, myocardial viability was assessed using pixel-tracking-derived myocardial deformation imaging and ceMRI to predict recovery of function at 9±2 months follow-up. For each left ventricular segment in a 16-segment model peak systolic radial strain will be determined from parasternal 2D echocardiographic views and the amount of late hyperenhancement (LE) and maximal thickness of myocardial tissue without LE using ceMRI. The hypothesis is that compared with segments showing functional improvement, those that failed to recover had lower radial strain and lower thickness without LE and higher LE.

Personalised Prospective Comparison of ARni With ArB in Patients With Natriuretic Peptide eLEvation...

Atrial RemodelingMyocardial Dysfunction7 more

Sacubitril-valsartan, an Angiotensin Receptor Blocker-Neprilysin Inhibitor (ARNI), currently marketed for the management of heart failure, has been shown to reduce cardiovascular morbidity and mortality in stage C heart failure with reduced ejection fraction. In stage C HFpEF, sacubitril-valsartan has also been shown to reduce left atrial volume index measured using echocardiography over a 9 month timeframe. The PARABLE study investigates the hypothesis that sacubitril-valsartan can provide benefits in terms of left atrial structure and function as well as left ventricular structure and function in asymptomatic (stage A/B HFpEF) patients. This is a prospective, randomised, double-blind, double-dummy, phase II study design. The patient population will have hypertension and/or diabetes together with preserved ejection fraction, elevated natriuretic peptide (NP) and abnormal left atrial volume index (LAVI, > 28 mL/m2).

Detection of Heart Conditions Using Artificial Intelligence

Left Ventricular DysfunctionHeart Failure

The purpose of this study is to evaluate how Eko AI performs in the real world, front-line setting where the availability of sophisticated, expensive diagnostic tools is limited, and where there is a premium on detecting VHD early in its course.
